Hero damage - help with my max dmg potential

To the best of my knowledge I am calculating my max damage for ONE (1) strike of Intrepid Slash correctly, but my observed max damage is significantly lower than my calculation.

It is important to note that I am not interested in my max damage with enrage and/or chance attack. Taking them out of the picture, I have:
Max ACA
Max Intrepid Slash
Max Combat Mastery
+6% Total Damage
My max damage range w/ buffs is 18632 (stop laughing at me)
Also, the monster has a 20% PDR


This is how I am calculating my max damage:
max damage range * skill% * Combo Atk Bonus * Total Damage % * ((Max Critical Bonus-1)/Combo Atk Bonus+1) * (1-(1-Combat Mastery)*PDRate) = Max damage

Or

18632 * 2.1 * 2 * 1.06 * ((1.5 - 1) / 2 + 1) * (1-(1-.4) * .20) = 91244

I have observed hundreds of critical hits and the highest one I have seen was 85XXX. Please tell me where I am going wrong here.

Thanks!

I think Combat Mastery works like it reduces 40% of what the monster's defense is? So if it's a 20% PDrate that means your combat Mastery makes it actually 12% PDrate.

Idk, who do I look like, Dusk? F3.

It's that way, yea. Add up your total -def %s and then that's how much of the 20% you negate. Since you only have your 4th job skill it'd be 0.2-(0.2*0.4) for PDrate. 12% like above.

Check out that last line. He already has it factored in properly.
(1-(1-.4)*.2) = .88
So he's multiplying out the 12% for pdr

TS: I'm not sure where you went wrong but I haven't kept up to date with heroes so I'm mostly useless here.

As far as I know, atk % shows up directly in your damage range, so you don't multiply it twice.

I don't think there's such a thing as "total atk%" though - it's either "total damage %" or "attack %"

18632 * 2.1 * (2 + .5) * 0.88 = 86080
2.1 = IS
2 + .5 = Combo + Crit
0.88 = def reduction

My formula is calculating PDrate at 12%...

Sorry, I have 6% Total Damage %, not 6% attack..... I wrote it wrong in my post. I fixed it now.

I still can't figure out the critical formula for heroes. I think there's where it goes wrong. Try and see if your top non crit is around 72~73k, at least that'll isolate the issue.

Edit: Would you happen to be lower level than the mob? Damage penalty is still present after big bang.

Ahhhh....I did'nt know about the damage penalty. I am 2 levels lower than the mob. I guess its either the damage penalty or wrong calculation of critical that probably explains it.

Also, good idea about looking at my highest non-crit damage. I will do that as well after I factor in the damage penalty to see if crit is being calculated wrong.

Thanks for your help, off to find damage penalty formula.

Normally, pre-BB, it was simply X% damage reduction where X was the level difference.
